I was wondering when this was going to come up.we all know we ran out of tires at the end of the season. So we had to start looking for another tire to run on and finish the season. Now don't get me wrong on this I was pretty happy with what we was using 6 inch wheel who to say that it won't happen with the 5 inch wheel over a period of time. I think we should get with the club members and take a vote on it. Be it 6 inch spec or open or 5 inch spec or open and decide which brand of tire is going be the best for the club cost wise and long lasting. Thanks that's my input. Edward 54
